TYPOGRAPHICAL CASTING-MACHINE.

Specification of Letters l 'atent.

Patented Apr. 2?, 1915.

Application filed August 21, 1914. Serial No. 857,803.

To all whom it may concern Be it known that I, J OHN It. Roenns, a citizen of the United States, residing at Brooklyn, in the county of King sand State of New York, have invented certain new and useful Improvements in Typographic-a1 (lasting-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical casting machines, wherein printing slugs or linotypes are cast in a slotted mold and delivered therefrom by an ejector blade advancing from the rear against the edge of the slug. In these machines the molds are adjustable in length to produce slugs'for printing columns or pages of different width, and the ejector employed is therefore constructed so that it may be varied in width to correspond with changes in the length of the mold slot.

For instance, in Letters'Patent of the United States, No. 967,976, to J. Rogers, is illustrated a composite ejector comprising a series of parallel longitudinal sections arranged edge to edge, and suitable devices whereby any desired number of sections can be connected with the ejector slide, while the others are left free and remain at rest. In actual practice, and due largely to the difliculty of reducing their size without impairing their strength, the active ends of the adjustable blades or sections ordinarily have a width of two ems, so that the composite ejector has a width of an even number of ems. In other words, while the length of the line in the mold may be varied by single units, or even less than that, the width of the ejector blade may be varied only by even multiples of such unit. That is to say, a 5-em slug would be ejected with a l-em blade, a 7-em slug with a 6-em blade, etc., because a further increase in the width of the blade would render its passage through the mold slot impossible. It is of course desirable to use a blade of substantially the same size as that of the slug to be ejected, and consequently I have devised means to permit its adjustment by differences substantially corresponding to those whereby the mold slot is varied; and specifically this is accomplished by giving different widths to the ends of the blades, for instance to some a width corresponding to an even multiple of a given unit, and to others a width prised within its spirit.

fore establishes the unit of variation.

corresponding to an odd multiple of such unit, so that by thelr appropriate combination the width of the composite ejector may be approximated with greater accuracy to the length of the slot.

In the accompanying drawing, I have shown my invention only in preferred form and by way of example, and as applied to the particular style of machine already referred to, but obviously many changes and variations may be made therein, and in its mode of application, which will still be com- Also it may be adapted to other forms of typographical machines, suchas those designed to produce type, dies or matrices, instead of slugs. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawing: "Figure l is a side view, partly in section and broken away, illustrating the application of my improve ments to a linotype ejector; Fig. 2 is a detached view of a series of ejector sections; and Fig. 3 is a perspective detail of the con nections to the ejector slide.

As is usual in linotype machines, or as disclosed in the said Rogers patent, the adjustable mold A is mounted in the mold wheel A, and the ejector is built up of a number of separate blades B, which are adapted to be connected by the individual elements C to the ejector slide C through the medium of the bar C the latter being adjustable vertically, in the well known manner, to select any desired number of the blades. The parts so far described and their mode of operation, may be of any approved or desired form, and in themselves constitute no part of the present invention.

As previously explained, it has been cus tomary to give a width of two ems to the blades B, which are added to or subtracted from the composite ejector, and this therIe- 11 order to diminish this unit, and thus be able to adjust the ejector more closely to the length of the mold slot, and at the same time avoid the undue weakening of the individual sections, I form the blades of different widths, corresponding respectively to even and odd multiples of the new unit, so that they may be combined to give the composite ner, I preferably form the main portion of v to 13-ems, 14-ems, l7-eins,

- blade its required size. Thus,

in Fig. 1 are shown one l-em section, three 2-emsections, one 3-em section, and one l-em section, these permitting the ejector to be arranged for instance to correspond either to a 13-em slug, or to a i l-em slug. In the previous practice the l3-em slug would have been ejected by a 12-em ejector. In F igi2 still another eX- ample is presented, embodying successive sections of 13-ems, l-em, 3-ems, l-em, 2-ems, .etc. In this case the blade could, beadjusted V l8-ems, -ems, 22-ems, etc. Of course, in each arrangement the particular conditions would control the size and disposition of the separate blades.

In order to avoid the weakening of the individual sections, and particularly those of the smallestwidth, such as one em, and to enable these sections to be connected to their actuating devices in the ordinary manthe blade of the usual size, and reduce it to the desired width at its active end, as by the recess E; and I form the adjoining blade with a corresponding projection D designed to engage in the recess E,when the blades are in cooperative relation.

As previously stated, I have shown my invention only in preferred .form and by way of example, and in a special" mode of adaptation, but obviously many modifications and alterations therein, and in its mode of application, will suggest themselves to those-skilled in the art, without departure from its scope.

'Having thus described myinvention, its

construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows g 1.: An ejector mechanism for typograph- Copies of thispatent may be obtained for ical machines comprising, in combination, a plurality of ejector blades, at least one of said blades being formed with a recess at its active end to reduce the width of said blade at such end, actuating means, and means whereby any selected number of blades may be connected to said actuating means.

2. An ejector mechanism for typographical machines comprising, in combination, a plurality of ejector blades, at least one of said blades being formed with a projecting portion at its active end to increase the width of said blade at such end, actuating means, and means whereby any selected number of blades may be connected to said actuating means.

3. An ejector mechanism for typographical machines comprising, in combination, a series of ejector blades, one of said blades being formed with a recess at its active end, and an adjoining blade being formed with a projecting portion seated in said recess, actuating means, and means whereby any selected number of said blades may be connected to said actuating means.

4. An ejector mechanism for typographical machines, comprising, in combination, a pair of ejector blades, one formed with a recess at its active end, and the other formed with a projecting portion seated in said recess, actuating means, and means whereby 'one or both of said blades may be connected to the actuating means.

In testimony whereof, I have afiixed my signature in presence of two witnesses.
